Legio II Concordialis

Legio II Concordialis was a Roman legion which was active during the 3rd century AD. Led by Marcus Flavinius Bucco, it pledged loyalty to the pretender emperor Quintillus during the Crisis of the Third Century, and it was sent to retake Asculum from Legio III Illyrica in 271 AD. However, it was defeated at the Battle of Asculum, during which Bucco was slain.
